It appears that most ASE users, even some experienced, are unaware of a really useful command that can save you considerable time. Maybe the reason it's little-known is because it's not in the menu.
If your alignment NAME changes after you've already finished your Paving Feature design in ASE, if you try to share the data again, ASE is going to output nothing at all because the alignment name stored in ASE's database doesn't exist anymore. The name of the alignment was ASE key to all the alignment's data.
Most people will undefine all the paving features, then redefine them again with the new alignment name.
There's a better way though... WAAAAY better.
Type "RPDB" at the AutoCAD command prompt.
This dialog will appear:
Select the old alignment name, then the new alignment name.
Share the data again
Create your new profiles now (the old one won't work anymore... For now)
